Actor and producer Fanshen Cox DiGiovanni, who is head of strategic outreach for Pearl Street Films, praised Jordan on Twitter.

She added: “On behalf of Pearl Street Films, Matt Damon, @BenAffleck, Jennifer Todd, Drew Vinton & I will be adopting the #InclusionRider for all of our projects moving forward.”

Media researcher Stacy Smith invented the term “inclusion rider” during a talk in which she came up with ways to show more women, ethnic minorities and people with disabilities on screen.

According to the University of Southern California, where Dr Smith is an associate professor, the concept of an inclusion rider is: “A-list actors can incorporate a clause in their contracts that stipulates that inclusion, both on camera and behind the scenes for crew members, be reflected in films.

“The rider states that women, people of colour, people with disabilities, and members of LGBT and marginalised communities who are traditionally under-represented be depicted on screen in proportion to their representation in the population.”
